Moving active window to a new workspace freezes the entire OS

Hi, when I try to move an active window to a new workspace using ‘SUPERSHIFT, 2’ my entire OS/hyprland freezes, even the keyboard commands doesn’t work. I use NixOS and here is my hyprland.conf. The only options is to restart the machine.

Using proprietary NVIDIA driver, by any chance?

Yes!!! Thanks for you reply.

Did you try with an open source driver?

No I haven’t. But I heard open source drivers are unstable and lead to a lot of glitches.

If this does not occur with a different driver, then we’d have narrowed down the cause.
